What we are about to tell you is classified and on no account should you try it at home. First you will need an evil adversary who, for the sake of mankind, needs to be liquidated (but not with liquid).
Secondly you will need to take a course in clay modeling until such time as you qualify to make a recognizable image. Thirdly light your furnace (yes we forgot to mention you will need a furnace) and recite the following:
’May GIBIL devour you!’
’May GIBIL catch you!’
’May GIBIL kill you!’
’May GIBIL consume you!’
Lob in effigy. You will also need an onion and a peeled date and be able to recite the above lyrics in Ancient Babylonian. If this doesn’t work try NUSKU instead. It may be GIBIL’s day off and NUSKU will be in charge. Mustn’t offend the gods. Things could backfire.
